HttpClient3实现HTTPS不校验证书

 正常情况访问https请求是自身是需要校验证书否则报SSL错误，实现不许导入证书到JDK即可正常访问https

 1、实现信任任何证书的类

package com.trunkbow.comm.serviceTest;

import java.io.IOException;
import java.net.InetAddress;
import java.net.InetSocketAddress;
import java.net.Socket;
import java.net.SocketAddress;
import java.net.UnknownHostException;
import java.security.KeyManagementException;
import java.security.NoSuchAlgorithmException;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;

import javax.net.SocketFactory;
import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;

import org.apache.commons.httpclient.ConnectTimeoutException;
import org.apache.commons.httpclient.params.HttpConnectionParams;
import org.apache.commons.httpclient.protocol.ProtocolSocketFactory;

public class MySSLProtocolSocketFactory implements ProtocolSocketFactory {

    private SSLContext sslcontext = null;

    private SSLContext createSSLContext() {
        SSLContext sslcontext = null;
        try {
            sslcontext = SSLContext.getInstance("SSL");
            sslcontext.init(null,
                    new TrustManager[] { new TrustAnyTrustManager() },
                    new java.security.SecureRandom());
        } catch (NoSuchAlgorithmException e) {
            e.printStackTrace();
        } catch (KeyManagementException e) {
            e.printStackTrace();
        }
        return sslcontext;
    }

    private SSLContext getSSLContext() {
        if (this.sslcontext == null) {
            this.sslcontext = createSSLContext();
        }
        return this.sslcontext;
    }

    public Socket createSocket(Socket socket, String host, int port,
            boolean autoClose) throws IOException, UnknownHostException {
        return getSSLContext().getSocketFactory().createSocket(socket, host,
                port, autoClose);
    }

    public Socket createSocket(String host, int port) throws IOException,
            UnknownHostException {
        return getSSLContext().getSocketFactory().createSocket(host, port);
    }

    public Socket createSocket(String host, int port, InetAddress clientHost,
            int clientPort) throws IOException, UnknownHostException {
        return getSSLContext().getSocketFactory().createSocket(host, port,
                clientHost, clientPort);
    }

    public Socket createSocket(String host, int port, InetAddress localAddress,
            int localPort, HttpConnectionParams params) throws IOException,
            UnknownHostException, ConnectTimeoutException {
        if (params == null) {
            throw new IllegalArgumentException("Parameters may not be null");
        }
        int timeout = params.getConnectionTimeout();
        SocketFactory socketfactory = getSSLContext().getSocketFactory();
        if (timeout == 0) {
            return socketfactory.createSocket(host, port, localAddress,
                    localPort);
        } else {
            Socket socket = socketfactory.createSocket();
            SocketAddress localaddr = new InetSocketAddress(localAddress,
                    localPort);
            SocketAddress remoteaddr = new InetSocketAddress(host, port);
            socket.bind(localaddr);
            socket.connect(remoteaddr, timeout);
            return socket;
        }
    }

    // 自定义私有类
    private static class TrustAnyTrustManager implements X509TrustManager {

        public void checkClientTrusted(X509Certificate[] chain, String authType)
                throws CertificateException {
        }

        public void checkServerTrusted(X509Certificate[] chain, String authType)
                throws CertificateException {
        }

        public X509Certificate[] getAcceptedIssuers() {
            return new X509Certificate[] {};
        }
    }

}

 

 2、使用（不需要把证书导入到JDK）

public static String send(String reqXml, String postUrl) {
    
        
        HttpConnectionManager connectionManager = new MultiThreadedHttpConnectionManager();
        HttpConnectionManagerParams params = new HttpConnectionManagerParams();

        params.setConnectionTimeout(10000);

        params.setSoTimeout(60000);

        params.setDefaultMaxConnectionsPerHost(10);

        params.setMaxTotalConnections(200);
        connectionManager.setParams(params);

        HttpClient httpClient = new HttpClient();  
        Protocol myhttps = new Protocol("https", new MySSLProtocolSocketFactory(), 443);   
        Protocol.registerProtocol("https", myhttps);   
        PostMethod method = new PostMethod(postUrl);
   　　 //常规的
　　　　/*
　　　　HttpClient httpClient = new HttpClient(connectionManager);
　　　　PostMethod method = new PostMethod(postUrl);
　　　　*/
        method.addRequestHeader("Content-Type", "application/xml;charset=UTF-8");
        try {
            method.setRequestEntity(new StringRequestEntity(reqXml, null,
                    "utf-8"));

            httpClient.executeMethod(method);

            byte[] abyte0 = null;
            abyte0 = method.getResponseBody();
            String res1 = EncodingUtil.getString(abyte0,
                    method.getResponseCharSet());

            String res = method.getResponseBodyAsString();
            Header locationHeader = method.getResponseHeader("Content-Type");
            String location = null;
            if (locationHeader != null) {
                location = locationHeader.getValue();
//                this.log.debug("The page was redirected to:" + location);
            } else {
//                this.log.debug("Location field value is null.");
            }
//            this.log.debug("返回报文http头中的编码信息 :" + method.getResponseCharSet());

//            this.log.debug("返回报文 :\n" + res);
            return res;
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            method.releaseConnection();
        }
        return null;
    }
